Features and Benefits
Semi-bottoming chamfers are used for blind holes. They have 3 to 3-1/2 threads.
Powdered Metal (PM) is tougher and more cost effective than solid carbide. It is commonly used on highly abrasive materials including high silicon aluminums.
V is a multi-layered TiCN coating that is harder and has greater wear resistance than TiN. It is used for applications in cast iron, steel, stainless steel, nickel alloys and aluminum. V is a proprietary coating exclusive to OSG Tap and Die, Inc.
